Does anybody have the dimensions for the shotgun house for the robotics competition?  I bought some PVC pipe to complement the joints which were provided, but I couldn't find any information about how long to cut each segment.  I did my best to remember how big the sample one on kickoff day was, but I think I may have made it a bit too big.

Also, what are the dimensions for the ramp/elevated ground?  I think the plateau was about 6-8 inches off the ground, but I'm not sure, and I don't know what the slope of the sides were.

Finally, what are we allowed to add to the kit?  Last year, several schools used foam-core board to create hoppers for the eggs.  Is this still allowed this year?  And if not, what are the guidelines?  We were promised information about this in the packet, but I have yet to find anything.
